Gaga will perform with Mark Ronson, with whom she collaborated on the song Shallow, while her A Star Is Born co-star Bradley Cooper represents the BAFTA Awards which also take place that same night.

Gaga tied for the third-highest number of nominations this year with five, for record of the year, song of the year, best pop duo or performance, and best song written for visual media for Shallow; and best pop performance for Joanne (Where Do You Think You're Goin'?).

She's previously won six Grammy awards, including two in 2010, three in 2011, and one in 2015 for her collaboration album with Tony Bennett.

Eye-popping: The Good Place actress put on an extremely busty display as she poured her curves in a plunging gown in coral and scarlet hues, which revealed her ample cleavage

Sultry: Her raven tresses were styled in her signature waves while her pretty features were enhanced with feline flicks of liner and a slick of bright red lipstick

Busty: The plunging dress featured spaghetti straps and a bustier top, which cinched in at her slender waist before flowing into an elegant crimped skirt

Dua Lipa will be making her Grammy stage debut on the show, where she'll be joined by St. Vincent for a special performance, while Adams will sing alongside Fantasia and Day in a tribute to late Queen of Soul Aretha Franklin.

However one star who will not be on stage - either performing or accepting an award, is Ariana Grande.

This is despite Ariana featuring prominently on billboards promoting the event throughout Los Angeles, and being nominated for both Best Pop Vocal Performance (for God Is a Woman) and Best Pop Vocal Album (for 2018's Sweetener).

The move comes due to a disagreement with Grammy producers over which songs she would perform, according to sources close to the situation.

An insider tells Variety that Grande felt 'insulted' after producers initially refused to allow her to perform 7 Rings,' the latest single from her forthcoming album Thank U, Next.

A compromise was reached whereby 7 Rings would be part of a medley, but Grande pulled out after producers insisted that the second song be of their choosing.

The source added that such stipulations were not imposed on other performers at the show.

The 61st annual Grammy Awards are produced by AEG Ehrlich Ventures for the Recording Academy. Ken Ehrlich is executive producer, Ben Winston is executive producer, Louis J. Horvitz is director, Chantel Sausedo is the producer, and David Wild and Ehrlich are the writers.
